Threats to web security

There are many threats to web security, including:

Malware

Malware is a malicious software that’s created to damage computer systems, steal sensitive information, or gain unauthorized access to a network. It’s installed on the computer without the user’s knowledge and can cause various problems, from slowing down the computer to compromising sensitive data.

• Viruses: A virus is a type of malware that attaches itself to legitimate files or programs on a computer. Once the infected file is opened, the virus can replicate itself and spread to other files on the computer, causing damage to the system.

• Worms: A worm is a type of malware that exploits vulnerabilities in software or hardware to spread itself over a network. It can cause significant damage to networks by consuming bandwidth and causing servers to crash.

• Trojan horses: A Trojan horse is a type of malware that’s disguised as a legitimate program or file but contains hidden malicious code. Trojan horses can be used to steal sensitive information or create a back door into the victim’s computer system.

• Ransomware: Ransomware is a sort of software that encrypts the victim’s files or locks them out of their computer until they pay a ransom. Businesses and organizations can experience substantial downtime and financial loss as a result.

• Adware: Adware is a type of malware that displays unwanted advertisements or pop-ups on the victim’s computer system. It’s often bundled with legitimate software downloads and can be difficult to remove once installed.
